I've been observing this issue on Debian system. After some exploration I found /usr/lib/mozilla/plugins/libjavaplugin.so pointing to non-existing /etc/alternatives/mozilla-javaplugin.so - perhaps left from some random upgrade.
Repointing that to existing /etc/alternatives/iceweasel-javaplugin.so fixed the issue. I know that Ubuntu uses mozilla corporation's firefox, not debian's rebranded iceweasel, however packaging has much in common and thus reason in ubunto could be similar. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1182128 Title: Java plugin not loading in Firefox 21 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/icedtea-web/+bug/1182128/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
